Question

if A B C are in ap and B=45 then tanAtanBtanC​

Answer 1

Step-by-step explanation:

write the values tan A tan B and tan C

Answer 2

Answer:

1

Step-by-step explanation:

as A B C are in Ap and B =45

so as we know B is the arithematic mean of A and C

so,B=A+C÷2

so A and C are 30 and 60 respectively

tan A = tan30⁰=1/_/3

tan B = tan45⁰=1

tan C = tan60⁰=_/3

tanAtanBtanC=1
